## How to Convert Seconds of Arc to Milliradians

To convert a measurement in seconds of arc to a measurement in milliradians, multiply the angle by the following conversion ratio: 0.004848 milliradians/second of arc.

Since one second of arc is equal to 0.004848 milliradians, you can use this simple formula to convert:

The angle in milliradians is equal to the angle in seconds of arc multiplied by 0.004848.

**For example,**here's how to convert 500 seconds of arc to milliradians using the formula above.

Seconds of arc and milliradians are both units used to measure angle. Keep reading to learn more about each unit of measure.

## What is a Second of Arc?

The second of arc is a unit of angle equal to 1/60th of one minute of arc or 1/3,600 of one degree.

A second of arc is sometimes also referred to as an arc second or arcsecond. Seconds of arc can be abbreviated as *arcsec*, and are also sometimes abbreviated as *asec*. For example, 1 second of arc can be written as 1 arcsec or 1 asec.

The second of arc is most commonly expressed using a double prime (″), though a double quote is often used as well. For example, 1 second of arc is most often written as 1″.

## What is a Milliradian?

A milliradian is equal to 1/1,000 of a radian. One milliradian is equal to 0.0573 degrees and there are 6,283 milliradians in a full revolution/circle. The milliradian is also a commonly used unit in mathematics.

The milliradian is a multiple of the radian, which is the SI derived unit for angle. In the metric system, "milli" is the prefix for thousandths, or 10^{-3}. A milliradian is sometimes also referred to as a mil. Milliradians can be abbreviated as *mrad*; for example, 1 milliradian can be written as 1 mrad.
